RATIO AND DRAW MEASUREMENT with arithmetic functions applicable to rate or total

TIME INTERVAL MEASUREMENT AND "STOPWATCH" OPERATION for periodic time measurement and one-time events

PHASE ANGLE AND DUTY CYCLE for offset in degrees and ON/OFF period in percent

PULSE-INPUT BATCHING with three relay outputs for automated batch control

In general, the 2140's two channels can accept PNP or NPN outputs from proximity switches and other pulse-generating industrial transducers; TTL or CMOS logic signals; magnetic pickup pulses down to 12 mV; contact closures; low-level outputs from all types of turbine flowmeters; or AC line inputs of up to 250 V-AC. The inverse period technique is used to calculate frequency or rate up to six places, and with an update as high as 25/s (see General Counter Meter Specifications).

The 2140's six-digit display can show any value from -999,999 to 999,999 with programmable decimal point. Scaling allows direct readout in desired engineering units (e.g., gallons or cubic feet based on counts from a turbine flowmeter). The channel to be displayed is selected via a front-panel pushbutton.

The peak value of the input signal is automatically captured and may be displayed via front-panel push button or a control signal received at the rear connector (since the last meter reset).

The built-in isolated excitation supply can power proximity switches and other sensors, if required.

In addition to the "R" OPTION (discussed, where applicable, in the following sections), 2000 Series options applying to the Model 2140 Counter Meter include:

Isolated Relay Outputs

Isolated Analog Output (the 2140's ability to output an isolated 4-20 mA signal which tracks a total may be unique among totalizers)

RS232 or RS485 Interface

BCD Digital Interface

Low AC/DC Power
